2.1.5. Power Monitoring and Line Fault Detection
In addition to reporting voltages and currents, the
ProSLIC continuously monitors the power dissipated in
each external bipolar transistor. Realtime output power
of any one of the six linefeed transistors can be read by
setting the Power Monitor Pointer (direct Register 76) to
point to the desired transistor and then reading the Line
Power Output Monitor (direct Register 77).
The realtime power measurements are low-pass filtered
and
compared
to
a
maximum
power
threshold.
Maximum power thresholds and filter time constants are
software programmable and should be set for each
transistor pair based on the characteristics of the
transistors used. Table 22 describes the registers
associated with this function. If the power in any
external transistor exceeds the programmed threshold,
a power alarm event is triggered. The ProSLIC sets the
Power Alarm register bit, generates an interrupt (if
enabled), and automatically enters the Open state (if
AOPN = 1).
This
feature
protects
the
external
transistors from fault conditions and, combined with the
loop voltage and current monitors, allows diagnosis of
the type of fault condition present on the line.
The value of each thermal low-pass filter pole is set
according to the equation:
where
is the thermal time constant of the transistor
package, 4096 is the full range of the 12-bit register, and
800 is the sample rate in hertz. Generally
= 3 seconds
for SOT223 packages and
= 0.16 seconds for SOT23,
but check with the manufacturer for the package
thermal constant of a specific device. For example, the
power alarm threshold and low-pass filter values for Q5
and Q6 using a SOT223 package transistor are
computed as follows:
Thus, indirect Register 34 should be set to 150Dh.
Note:
The power monitor resolution for Q3 and Q4 is different
from that of Q1, Q2, Q5, and Q6.
